Please don't die you're too young and talented and mentally stable to die you have such a promising life ahead of you. :c
Why does it need that many eyes if it lives in a dimly-lit "foggy"-due-to-spores, underground area?
It's a sentient fungus that walks around and talks and you're worried about its
eyes??
*cough* All kidding aside, though, I figure we can just chalk it up to nonstandard biology, given the unusual nature of the circumstances. Given Truffle is a living fungal mass, it wouldn't even have the same sorts of eyes as Metazoa, and as such their presence and function would be analogous, not homologous, to our own. They'd work differently, especially considering the dialogue where "everything started glowing blue" implying that its natural habitat, which to
us appears to be
constantly glowing blue, doesn't appear that way to its default visual perception.
Alternatively, maybe it just doesn't see well to begin with. More eyes doesn't necessarily mean better vision if the eyes are primitive. Just look at insects with ocelli. Perhaps the big eye does most of the visual intake and the two smaller eyes have a more basic function, such as picking up motion, or maybe even being mild heat sensors. Who knows how sentient fungi perceive the world!
...or its just to make it look cool.
Or, you know, it could be that.
To be honest, I look at the sprite and see a single eye, but as I started sketching, I just liked the idea of using eyes as an additional layer of asymmetry to give off a very alien appearance.
I just like to overthink things in addition to drawing purely for the fun of it. :>
